Description
Schwungrad mit angegossener Schnurrolle und einem Ausgleichsgewicht für Nähmaschinen Bei Nähmaschinen ist es bereits bekannt geworden, bei Schwungrädern mit angegossener Schnurrolle ein Ausgleichsgewicht anzuordnen, welches auf der Armwellenbüchse in dem hinter dem Handrade gelagerten Hohlraum angeordnet ist, und muß dieses von innen angebracht werden. Diese Anordnung ist aber unpraktisch, da beim Anbringen des Ausgleichsgewichtes das Schwungrad erst abgenommen werden muß, um das Ausgleichsgewicht anzubringen. Von diesem Bekannten abweichend ist vorliegende Erfindung gedacht, deren Wesen darin besteht, daß das Gewicht in den Hohlraum des Schwungrades von außen einsetzbar und mit der Armwelle fest verbindbar ist.Flywheel with cast pulley and a counterweight for sewing machines In sewing machines it is already known for flywheels to arrange a balancing weight with the cast-on cord roller, which is on the arm shaft bushing is arranged in the cavity stored behind the handwheel, and this must be of be attached inside. However, this arrangement is impractical because when attaching of the balance weight, the flywheel must first be removed in order to remove the balance weight to attach. Deviating from this acquaintance, the present invention is intended to whose essence is that the weight in the cavity of the flywheel of can be used outside and can be firmly connected to the arm shaft.
Auf der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt und zeigt Abb. z Rückansicht der Maschine mit Schwungrad (Handrad), Abb. 2 Schnitt durch das Handrad mit fortgelassener Feststellvorrichtung, Abb. 3 Vorder- und Seitenansicht des Ausgleichsgewichtes. In dem Hohlraum a des Schwungrades b ist ein Ausgleichsgewicht angeordnet, welches aus einer Scheibe d' und einem Gewicht d" besteht, wobei die Scheibe d' mit einer Nase e versehen ist, die sich in eine der bekannten Nuten f der Armwellenbüchse g einlegt, die zu diesem Zwecke etwas zurückgesetzt ist, um die Nase i aufzunehmen. Das Gewicht d" ist derart angeordnet, das es der Kurbelstange la des Untergetriebes gegenüberliegt. Durch die Anordnung wird erreicht, das Ausgleichsgewicht ohne Abnehmen des Hand- bzw. Schwungrades ausbauen zu können, wobei nur die Feststellvorrichtung des des Handrades abgeschraubt werden muß.In the drawing, the invention is shown in an exemplary embodiment and shows Fig. Z rear view of the machine with flywheel (handwheel), Fig. 2 section through the handwheel with the locking device omitted, Fig. 3 front and side view of the counterweight. In the cavity a of the flywheel b a balance weight is arranged, which consists of a disk d ' and a weight d " , the disk d' is provided with a nose e, which is inserted into one of the known grooves f of the arm shaft bushing g, which is set back somewhat for this purpose in order to accommodate the nose i. The weight d ″ is arranged in such a way that it lies opposite the connecting rod la of the lower gear. The arrangement enables the counterweight to be removed without removing the handwheel or flywheel, only the locking device of the handwheel having to be unscrewed.
